Foundations
How to read peptide research
Start with study quality, product status, compounding rules, and product-quality risks before comparing peptide claims.
What is a peptide?
Peptides are a broad category. Evidence quality depends on the molecule, product, route, claim, and source.
How to read a peptide page
A short tour of the sections on every full peptide profile: what each layer tells you, and where to stop if you only need the bottom line.
How we grade peptide evidence
Why one overall peptide score can hide important differences between human evidence, safety signals, legal status, and product quality.
FDA and compounded peptides
FDA-approved medicines, compounded drugs, investigational products, and research-use products are not interchangeable.
How to read a COA
A certificate of analysis is a starting point, not a verdict. What to check before trusting one.
Storage and reconstitution basics
Why most peptides ship as freeze-dried powder, how reconstitution changes stability, and the math behind drawing an accurate amount.
Peptide legality, explained
Approved, compounded, investigational, research-use-only, and gray market: what each status actually permits.
